Instead of kudos, they received mostly Facebook messages like this one from a mother:

"I used to feed Cheerios to my first child all the time. Now that I am
better educated on GMOs, I am DISGUSTED at the fact that I was naive
enough to believe that at the time I was actually feeding her something
healthy. I know much better now, and will never again let another
Cheerios pass my children’s lips until they are GMO-free."
